UITapGestureRecognizer(双击)
双击,如单击,也使用 UITapGestureRecognizer
。你只需将 numberOfTapsRequired
设置为 2
。
迅速
override func viewDidLoad() {
super.viewDidLoad()
// Double Tap
let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleDoubleTap))
doubleTapGesture.numberOfTapsRequired = 2
doubleTapView.addGestureRecognizer(doubleTapGesture)
}
// Double tap action
func handleDoubleTap() {
label.text = "Double tap recognized"
}
笔记

- 你可以通过将
numberOfTapsRequired
设置为3
来识别三次点击。
